Either that or a creepy old bird, he wiggles his eyebrows when he gives you coffee. It just struck me as funny when I noticed. Like right after you drink your coffee he wiggles his eyebrows twice really quickly and it makes me laugh every time. 
And hes a pigeon and gives you white pigeon milk like wtf brew where does that stuff come from i dont want to know
And why am I expected to remember every customers brew but have to give Brewster my order every time? Double standards.
